Put 1 as the next digit of the answer. 
Result so far: 50365.1
The remainder is 127 after subtracting 333 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 10:
If we divide 1270 by 333, we get 3 and a remainder of 271.
Put 3 as the next digit of the answer. 
Result so far: 50365.13
Deduct 999 from 1270 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 12:
333 goes into 460 1 times with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 50365.1381
If we subtract 333 from 460, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 13:
The number 333 fits into 1270 3 times, leaving a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 50365.13813
If we take 999 away from 1270, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 14:
333 goes into 2710 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 50365.138138
Deduct 2664 from 2710 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
460 divided by 333 is 1 with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 50365.1381381
If we take 333 away from 460, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.
